Letters Patent No. 98,418, dated December 28, 1869.

xmnovsmim ns spant@ connexe The Schedule referred to in these Letten Patentand making parte! the lame.

To all whom it may concern Be it known that I, L. RODENHADSEN, of the city and county of Philadelphia, and State .of Pennsylvania,-have invented certain. new fand useful Improvements in Spring-Couplings for Galriages, Sac.; and -I 'do hereby declare the following to be a full, clear, and

- exact descriptionthereo,sufiicient to enable others skilled in theart to which my invention appertains to make and nsethe same, reference being hadto the accoinpanying drawings, making'part of this specifica' tion, in which- Figures 1 and 2 are elevations of two vsections, comprising acoupling, as illustrating my invention.

Figures 3 and. 4 are elevations of "a coupling 'made in one` piece, and likewise illustmting my invention.

Similarr letters oi' reference indicate corresponding 'parts in the several iigurns.

It is at present customary to construct the coupling to which the ends of springs are secured, of wroughtiron. This is quite an expensive item in the manufacture of carriages and wagons, partly owing to the v In iigs. 1 and 2, I show a sectionall coupling, in which the part A is made separate from the part B.

Iform a groove or depression, a, in the under side 'of the arch of the part A, and this groove receives the the arch b of the part B.

l*By thus making the couplingv in two parts, the springs are allowed more play, and, therefore, have moreperfect and less limited bearings.

4 All shocks are in part checked, owing to the give between thesections, and there is thereby but little opportunity 'for breaking or fracture thereof.

ln order t'orender the. sectional coupling still more complete, I form. it of malleable iron, whereby I save at least two-thirds ofthe cost of the couplings now in common use. The strength of malleable iron is toowell known to require further reference.

I produce a. superior .article of manufacture, com-A bining utility, strength, and eheapness.

.Having thusdescribed my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The two-part coupling A B, the part A being provided with groo'ye A, substantially as and for the purpose describedtv '.lhe above signed by me, this day of 1869.
